CORPORATION OF NEW YORK RADIATOR Application filed January 31, 1927, Serial No. 164,947. Renewed October 9, 1929.

My invention relates to improvements in radiators and is more particularly directed to that type of device wherein a heated medium is used for increasing the temperature of a room or the like.

The object of my invention is to provide a heating apparatus wherein the elements used therein for distributing the heat are con structed in a simple and efficient manner.

The main object of my invention is to provide a unit for distributing heat so constructed that when the cold air travels over its surface the same will be heated throughout a longer period than that now generally employed.

A further object of my invention is to provide a heating unit composed of one or more flattened pipe sections, said sections having thereon a plurality of radially extending fins, the purpose of the flattened pipe being to increase the heat radiated from the pipe and fins during the passage of cold air thereover. It will be noted that by use of flattened pipe sections a more uniform degree of heat is radiated from the pi es and the distance from the surface of the attened portions to the outer edges of the fins give out a greater degree of heat by reason of the cold air contacting therewith than a round pi e section of equal internal area.

Furthermore a flat pipe having the same internal area as a round pipe and carrying a heating medium will give out its heat'to the surrounding walls more rapidly than a round pipe, the reason of this being that the distance through which the heat travels to reach the conducting walls is less.

With these and other objects in view the invention consists in a general arrangement and combination of parts which will be hereinafter more fully described in the following specification and specifically set forth in the appended claims, when taken in conjunction with the accompanying drawings, in which:

Figure 1 is a side elevation of my improved heating unit;

Figure 2 is an enlarged detail view taken on the line 2-2 of Figure 1;

Figure 3 is an enlarged section view taken through the various connections for the several sections of the unit.

Figures 4, 5 and 6 illustrate in detail the specific structure of these connections.

Figure 7 is an enlarged sectional view showing a pipe section having thereon a plurality of heat radiatingfins.

Figure 8 is a detail view illustrating the manner of connecting the heatdistributing section with the usual supply pipe.

Figures 9, 10, 11 and 12 illustrate in detail the elements employed in forming the connection illustrated in Figure 8.

Referring to the accompanying drawings in detail wherein like reference characters denote corresponding parts throughout the several views, the numeral 1 indicates generally a heating unit formed in the manner which I will hereinafter more fully describe, this unit being composed of one or more sections and each section being connected to a common supply pipe.

As disclosed in Figure 1 the heating unit is composed of a plurality of pipe sections 2,

y the intermediate portion of each being fiattened as disclosed in Figure 2, and by reason of the flattened portion the cold air passing transversely by will remain in contact with the pipe section a longer period than if a pipe section of equal internal area having a roun cross section was employed. This flattened portion, which I have indicated by the numeral 3 has positioned thereon a lurality of fins 4, each of which is formed 0 a piece of sheet metal having in its central portion an opening which corresponds to the shape of the pipe section 2, and as disclosed in Figures 2 and 7 that portion of the metal around the central opening is bent at right angles to form a flange 5, through which the fin is connected to the pipe 2, and at the same time forms a spacer between the fins.

It is of course to be understood that the pipe section 2 may be of any desired shape that will permit air to remain in contact with the pipe section a longer period than should the section be cylindrical in form. Furthermore the fins 5 may be connected to the pi e section 2 in any suitable manner, such as oy solder-= ing or fusing the flange 5 to the exterior of the pipe section 2.

The end portions of pipe section 2 after fins have been placed thereon, are made round, and each end has positioned thereover a flanged coupling 6., as disclosed in Figure 8 and resting upon the flange 7 is the flanged or bent over end of the pipe section 2 which is formed after the fins are in place. The coupling (l is interior-1y threaded as indicated at 8 to receive therein a suitable clamping ring 9, which when inserted within the coupling holds the flanged end of the pipe section 2 upon the seat 7. thus forming an air tight joint. If desired the clamping ring 9 may be eliminated and suitable fittings inserted in lieu thereof as illustrated in Figure 3 of the drawing. The form disclosed in Figure 8 is particularly employed when a one pipe structure is desired, the supply pipe being indicated by the numeral 10.

As disclosed in Figure 3 of the drawing wherein I have illustrated a heating unit composed of three pipe sections, indicated by the numerals 2, each of which has its end portion flanged similar to that disclosed in Figure 8 and being received within a flanged coupling 6. In this structure I have eliminated the clamping ring 9 and have inserted in place thereof the various fittings which form the means for connecting the pipe sections to a suitable supply. One pipe section 2 has abutting against its flanged end a right angle connection 11. The intermediate heating member 2 has its end portion connected in a similar manner to that previously described with a cross connection 12, one threaded portion of which is inserted within the coupling 6 while its aligned opening has in threaded engagement therewith a supply pipe 13 through which a suitable heating medium passes. The cross part of the section 12 has one end connected to the right angular conmotion 11 by means of a nipple 14, the end portions of which are exteriorly threaded and provided with right and left handed threads as indicated at 15 and 16 respectively. The nipple 14 is further provided with an internal flange having therein an irregular opening 17 which is adapted to receive therein the end portion of a suitable tool or the like which is employed for turning the nipple and form ing the connection between the elements 11 and 12.

The remaining heating section, as disclosed in Figure 3, has its pipe section 2 connected to a suitable three way connection 18, in a manner similar to that of the other sections, one outlet end of the connection being closed by a suitable cap or the like 19 while its other end receives therein a nipple 20 through which the connection to the element 12 is formed. The nipple 20 being of a structure similar to that of the nipple 14.

While I have disclosed in the drawings the connections formed at one end of the various heating sections of the unit it is to be clearly understood that the other ends of the heating sections are to be connected in a similar manner and provided with an outlet pipe for the passage of condensation therefrom. Furthermore in forming units of this character it is to be understood that one or more sections may be employed and when a plurality of sections are connected of a smaller or greater number that that illustrated in Figure 1 the connections of the several sections will of course, vary but it is to be clearly understood that the structure,- operation and general arrangement of these elements will not vary to any great extent from the structure illustrated in the drawm s.

ln the event it is desired to merely have a heating unit composed of one section the connections at the end of this section will correspond to that previously described with the exception that the supply pipe will be inserted within the clamping ring of the remaining in contact with the pi e section a greater length of time and there insuring a greater heat radiation than in devices wherein a cylindrical pipe section is used.

From the foregoing it is thought that the many advantages of the hereindescribed invention will be clearly apparent to those skilled in the art without further description, and it is of course to be understood that various changes in the size, shape and proportion of the various elements may be resorted to without sacrificin any of the advantages or departing from t e spirit of the invention.

Having thus described my invention, what I claim as my invention is:

1. A radiator of the class described c'omprising a plurality of pipe sectionshaving flattened intermediate portions and rounded flanged ends, circulating means for maintaining the pipe sections in spaced relation to each other and detachable therefrom including pipe connections having circular openings therein, the flanges of said rounded pipe ends adapted to bear against said connections around said circular openings and clamping rings for clamping said flanges to said connections, a supply pipe connected to said circulating means, a plurality of apertured heat radiating fins positioned about the flattened portions of each of said pipe sec tions, and each fin being formed of heavy metal and having a flange around its aperture fitting snugly to the pipe section for maintaining the fin at right angles thereto and in a spaced relation with respect to the adjacent fin.

2. A heating radiator unit of the class described composed of atube havinga fiattened intermediate portion and rounded flanged ends, finshaving oblong openings adapted to snug-1y receive said flattened portion, a supply pipe and means for connecting said rounded flanged end to said supply ipe.
